Definitions

  • the present invention relates to an occluder according to the preamble of patent claim 1.
  • Occluders are implants used to occlude passageways or openings in circulatory systems, such as blood vessels or shunt connections, and are typically positioned and expanded via a sheath introduced into a vein. Occluders are used in particular for closing openings in the heart or in another body passage of the human or animal body. They serve, for example, to occlude a persistent ductus arteriosus (PDA), an atrial septal defect (ASD) or a ventricular septal defect (VSD). Other applications in the human and animal body are possible.
  • PDA persistent ductus arteriosus
  • ASD atrial septal defect
  • VSD ventricular septal defect
  • occluders In the prior art, the most varied embodiments of occluders are known. You can, for example, be designed as a spiral spring or can be stretched like an umbrella. You can also close the passage only from one side or from both sides. These occluders can usually be made into an elongated shape so that they can be brought by means of the catheter to the passage, which is to be closed. There, the occluder is released and he takes either automatically or led his expanded form of use.
  • WO 2005/074813 discloses an occluder, according to the preamble of claim 1, with two expansion units and two closure bodies, which rest on one side of the passage.
  • This occluder is in the Figures 1 and 2 shown.
  • the expansion units are formed by wires 3, which are held with a first end in a first coupling part 1 and with a second end in a second coupling part 2.
  • the closure bodies are circular membranes 4, 5, which are penetrated by the wires 3.
  • these membranes 4, 5 are stretched by the wires 3. They close the body passage from both sides.
  • the coupling parts 1, 2 can be in accordance with the expanded appearance FIG. 2 stuck together, so that the occluder is fixed in this form.
  • WO 2007/115117 is an occluder with both sides of the body passage adjacent expansion units known, the distance between the expansion units is adaptable to the depth of the passage.
  • the occluder according to the invention for closing an opening in a circulation system can be converted from a compact appearance extending along a longitudinal axis into an expanded appearance extending transversely to the longitudinal axis.
  • the occluder has a first expansion unit and a second expansion unit, which lie in the expanded appearance on each side of the opening.
  • the occluder further includes a first coupling part and a second coupling part engageable with each other so as to fix the occluder in its expanded appearance.

According to the invention, this region is designed to be stretchable along, ie in the direction of, the longitudinal axis. Preferably, it is stretchable against a restoring force, that is designed to be resilient or elastic.
  • the distance between the two expansion units and, if present, between two closure bodies can be adjusted automatically. If the occluder is placed in the body opening to be closed and brought into its expanded appearance and the two coupling parts are connected to each other, the depth of the opening or the thickness of the surrounding body wall determines the distance between the two expansion units.
  • the stretchable area is stretched accordingly, so that the expansion units and, if present, the closure body, adapt to the wall and can lie as flat as possible. The opening is thereby optimally closed and acting as a fixing expansion units are optimally against the wall.
  • the expandable region may be provided on the distal and / or proximal coupling part.
  • Proximal here means the doctor and thus the entry point in the body facing and distal to the doctor facing away, so patient side.
